AIR, OIL, AND GAS BURNER.

` 'rox, a citizen of the United States. residing at Elton, in the Parish of Jefferson Davis and VState `of Louisiana.' have invented certain new and useful Improwiiiients in Air, Oil, and Gas Burners, of which the following 1s a specification.

32Min irri-guiar size of flame which` may at one r My invention relates to new and useful improvements in gas burners and more especially to that type employing a gas embodying a mixture of oi] and air formed within the burner casing before passing.;` to the burner jets or nozzles.`

Among the various objects of the present invention is to, provide; First, a gas burner, a portion ofthe casing' of which provides a chamber in which the constituent partsof the gras are thoroughly adinixed which parts in they presentcase are. oil and air;` second, to provide in a unitary structure, an 4oil reservoir. a mixingg` chamber, a inessure supply device, a vcompression chamber, `burner nozzle vand ignition means third. to provide a gas burner having' a self contained means for,.compressing the gases mixed in the apparatus and for keepiiif,r said gases under constant pressure; fourth, to provide in association with said pressure devicev which keeps the pressure of the gas constant. a compression bowl which maintains the pressure of theg'ases at the. nozzle tips uniform thereby avoiding' pulsating; currents. of gases issuing from' said nozzlesfwhich causes moment .grow small and at anotheiilarge de- 5 the burner mouthand'in' .pending upon the storage tanks. i .y y,

An obiection. which has `.been heretofore experienced Lwith iariou'stypes of, combined pressure '"inL theA usual oil and. air burners with 'wliichlam familiar is that the oil and air werefed .from different sources underivaryiug.,:heads yof pressure, the oil and air l'being' ffed" 'to, substantially a. vnumber of` instances the pressure behind .the two liuids beingata varianceI the mixture will vary in its proportion of constituent elements as well as' vary in its Velocity when ing from the burner'mou'th.'"

ith myapparatus the gasesare thoroughly mixed at. a time ofthe time fromiwhich they-emerge from the burner mouth, .and 'between which pefrom the riods of mixtureV and en'ierging burner mouth they are subjected in their Application filed November 25, 1914.

mixed state to'a pressure in addition to and independent of the head under which they ow into the mixing chamber. Further, although the pressure creating' means ,should vary from one cause or another, the provision of thecomfpression bowl would always hold the pressure of the gases as they emerge from the burner mouth uniform so long as the apparatus was in operation.

lVith the foregoing explanation of the advantage of my invention over and as coinpared with previous gaseous fuel burners with which I am familiar I now refer to the drawingsforming a part of this speciication in which`.,

Figure l is a longitudinal sectional elevationof my complete apparatus illustratinfbr its application to ,use with a horizontal water tube boiler of the usual type. Fig. 2 isy an end elevation of the apparatus viewing the same from the direction of the arrow in Fig..l. and Fig. 3 is an v'end elevation of the iii-ner nozzles viewing` the saine from the direction of the arrow B in Fig. l.

heferring now more specifically to the drawings by numerals of reference, l indicates the casing" of the apparatus. the same being supported in proper position with relation to the boiler 3 as herein shown by legs or standards l suitably secured to y:said casing and resting' en the floor or other support as shown. The casing l is prefgenerally conical in cross section and is built in sections united together to form af 'unitary structure by flanges G, 7, and 8; That which I will term ythe firstsection l saniebeingr cylindrical in cross-section and [provided 'with a flange 10 having an annular series of ,uniformly spaced valve seats ll which cooperate, *with ay series of pop-valves 12,15' the.' stems 1i of which are slidably mountedv in sleeves l5' carried by an annular series of spacingi members 16. A spring 17 k,normally holds eachv valve to its seat inthe rusual manner, the. tension of the spring belin'g regulated by the nuts 18 to such a degree that whilenormally7 seateththey will become unseated by exhaust pressure within the apparatus to'allow air to be fed thereto for purposes hereinafter specified.. Mounted concentrica'lly within the cylindrical section 9 and spaced from the latter bv tlie'spacing members l(` `1s an o-il supply reservoir 17 which is adapted to supply oil to the apparatus through the medium ot an annular` will designate by 9 the ioo loil valve to' which-1t isy 'coincident thustglikf thoroughly mi d and-ther@isfnosteigmin, A i vide motwepowerlfor the,turbmetllemploy' roturnmwineiO "leadixxgffrom" the batteryll" iid being fgrouhded" in the" metal` dome 1 at "1251 series of valves 18', said valves 18' being of steam `to operategthe turbine, the clutch `placed preferably near .theedge oflinside"` `36is `thrown outandrthe ompressor driven face, 19 ofV the.` reservolr and a valve in the bythe steam turbine, thel valve 32 being.r op- `annular series of' oil valves being arranged eratedY toaduiltA steam in required quantiadlacent a valve in the annular series Qfair l f tiesto suld steam turbine.
